When you talk to the last priest at Liberty Bay, he tells you that the next time to want to "Mumbo Jumbo" (magic) you better visit Chondur at Meriana. Once you visit Chondur and ask him for the stake, he is amazed to know that so many persons were needed for the blessing spell and he recommends you to visit him directly next time you need one.
It is important to mention that you require access to Meriana which can be easily obtained in around 5 minutes.
Chondur can make one blessed stake per week.
